IMPROVEMENT IN CHAIRS.

Specification forming part of Letters Patent No. 168,828,

dated October 19, 1875 application filed November 3, 1874.

To all whom it may concern:

Beit known that I, A. H. BRICK, of Winchendon, State of Massachusetts,have invented certain Improvements in the Manufacture of Chairs, ofwhich the following is a specification My invention relates to theconstruction ofchairs and connecting mechanism, and is designed to allowthe chairs, after they are finished, to be partly taken apart and packedin a much smaller place, while they can be readily put together againfor use without glue or any need of marring the finish of the chair,applying to all kinds of chairs, and to upholstered work with specialadvantages.

The drawing represents a chair constructed in accordance with myinvention.

Figure 1 is a view of a chair complete. Fig. 2 is one side of the chairas removed for packing and shipping; Fig. 3, the back. Fig. 4 is a viewof the under side of the seat, to show connecting device. Figs. 5, 6, 7are different forms of connecting device drawn on a larger scale thanthe rest of the drawing.

In chairs which are to be partly taken to pieces for packing andtransshipment, it is customary to frame permanently together the wholeback of the chair, including the main posts ortall standards of thechair. The side rounds or cross-pieces are to be put in when the chairis finally set up, and the chair is likely to give way on the side.

My improved method is to frame permanently the whole side of the chair,as in Fig. 2, thus including one front and one back post in the sideportion. This forms aflat portion, and it packs in smaller compass thanthe usual back. X is the high back post and leg, supporting the back byits upper part, and Y is the front leg. These I connect firmly together,as by the arm V and rocker Z. In the style of chair shown the front legY is continued up and inclined to meet the back post X, and forms thearm V, and the rocker Z, uniting the lower parts of the legs Y and X,performs the office of a bar or round. The inner partof the back isframed with the upper back crosspiece, which latter may be above theside pieces, as seen in the drawing, or it may as Well be made to gobetween them, as in the common chair. The seat is framed in the usualmanner.

A chair made in this way may be upholstered in any manner, as well ascaned, and still be taken down and packed for transportation as readilyand conveniently as a caneor wood bottom, and chairs made in this wayhave the advantage of stiff permanent sides, on which the main strain ofthe use comes, thus making a much more durable chair.

The method of connecting the parts is as follows: On the under side ofthe seat, Fig. 4, at each of the corners, is a piece of metal, A,fastened by screws or otherwise, in which is a hole, to which is fittedscrew B. This construction is seen in Fig. 5. The screw B passes throughthe side of the chair, as seen in Figs. 1 and 2, and the side and seatare securely joined.

The same device may be applied to the upper part of the chair of thecommon constructlon.

In the rocking-chair, or in any chair where the top extends beyond thesides, a piece of metal, 0, Fig. 2, may be inserted in the side piece,which piece of metal enters a mortise, D, Fig. 3, in the upper part ofthe back of the chair, and a screw (not seen in the drawing) is passedthrough the hole in G. Through the seat of the chair at E a screw passesupward into the lower part of the back at E.

The metallic device may also be made as seen in A, Fig. 6, with aprojecting bolt, to

which a nut, 13, is screwed on the outside.

Another form of the device is represented in Fig. 7, in which 'A is alarge screw with coarse thread, to be inserted in the side of the seat,and the screw B is put into the small hole in the center of A.

The piece of metal A,-instead of being made thicker for the hole toreceive the screw, may be merely a thin piece of metal bent over theedge, and the hole he made in the bent portion or the piece A may befastened directly to the edge, and the screw B be inserted through A,instead of into the edge, as in the drawing. Either form of the devicemay be used at E, or to fasten any other cross-piece of the chair, ifsuch are used.

A slight notch may be made in the side screws B and nuts A, the backbeing supported by the high posts X, substantially as and.- for the 1purposes described.
